Title: Dungeon Run - keep_fountain Missing Barrier Blocks

Summary: In the Dungeon Runs, there is a keep floor where there aren't any barrier blocks to prevent the players from going on top of the dungeon rooms. The room is keep_fountain

Priority: C
doesn't really break anything.

Server: Dungeon Runs

Steps to Reproduce: 
Do a dungeon run (keep would be easiest so you can find it faster)
Find the keep_fountain room
Swim up the fountain

Expected result: you'd stop at the top.
Actual result: you go through the top and stand on top of the dungeon rooms

proposed fix: add barrier blocks at the top, or stone bricks

Screenshots: first one - the room. second one - being above the room.
